Erbium Laser Garnet Pendants in Sterling Silver (YAG:Er Jewelry)

These are faceted Er:YAG (Yttrium Aluminum Garnet) Pendants in 925 Sterling Silver

Used in lasers, Erbium YAG has a very strong color change, and will go from orange to pink depending on lighting.  Depending on the lightbulb type (even changing between different LEDs), or when illuminated by computer monitors or phone screens, the gem keeps shifting.  It's easily visible under real world lighting conditions so the stones look different throughout your daily routine.

This extends to phone cameras as well - one of these might look pink to the eye and yellow to your phone!

With a hardness of 8.5 it is ideal for use in jewelry.
